when pulling out the old valve guides of my alfa 75 3.0v6 engine the bores of the exhaust valve guides got damaged. Did the removal with a heated cylinder head. Now interfearence with the guide and the head is about 0.005mm and it shoud be according to the manual more than 0.015mm...

Is it oke to clean up the bores and glue them in with the heat resistand locktite 270?
Are there any other solutions?
